Answer 1

If crossing over did not occur there would be no diversity among organisms.

Step-by-step explanation:

Crossing over and independent assortment are the two phenomena of meiosis by which genetic and physical diversity occurs. If crossing over did not occur then there would not be changes in the physical features of children. No physical diversity would be produced. Children would have the same physical features as the parents. Each chromosome would be identical to one of the parents and hence there will be reduced variations.
